Sony has announced a more powerful version of its PlayStation 4 console at an event in New York.
The PS4 Pro will be able to render games in sharper quality for ultra-high definition 4K televisions.
A cosmetically redesigned, slimmer PlayStation 4 was also announced and will be sold at a cheaper price.
One analyst said releasing an upgraded console so soon after the PS4's debut in 2013 took the company into "uncharted territory".
Sony typically makes cosmetic changes to the PlayStation between major releases, but this will be the first time it will have two consoles on sale with significantly different graphics capabilities within the same generation.
"We realised that for the very highly-discriminating gamer there is always a desire for advancement, and they want it in this generation," said Sony's Andrew House.
Since outputting games to 4K televisions requires more computing power than HD, Sony said the PS4 Pro would have more than double the graphics processing power of the PS4.
However, unlike Microsoft's Xbox One S, the PS4 Pro will not be able to play 4K Blu-ray movies - a move which has disappointed some fans.
"The PlayStation is primarily a gaming platform, and everything we do is to make the gaming experience as seamless as possible," Jim Ryan, head of PlayStation Europe, told the BBC.
